throttle body cooling ?
Another problem !!!
I just removed the throttle body. The lower coolant hose is still connected and the vacuum line at the bottom is disconnected. Is it ok to just remove this hose and plug the hole in the intake? And is the vacuum supposed to be hooked up to the tb?

First thing I did with this '88 and the prior one was the TB coolant bypass mod.
Check front of your radiator for debris collection, check radiator for proper coolant flow & pressure, replace the T-stat. I don't like the engine running in to 200+deg. temp range, so have always (for >17yrs) run a 160 deg. T-stat.

Read Bfenty's PSA on summer cooling.
BTW...240 is not THAT crazy of a number but it should go lower. Again, clean your radiator and look for debris BETWEEN the AC condensor and the radiator.

Fill in your profile. What year is your car. The fan turn temp is 235* +- a few. 240* is pretty warm but not "turn off the A/C" hot. Do clean between the rad & a/c condenser and report back.

For some reason no one mentioned that the coolant flows through the throttle body to warm it in cold weather, not to cool it in warm weather.
That's why so many people bypass it. Not really needed a lot of places.

It is a 1989 I have the fan set to bypass the ECM. It has separate wiring and comes on at 190 and doesn't shut off until 180. The fan is an aftermarket fan that produces about 2500 cfm...

that's...a lot. You shouldn't see 230 with a fan like that. my stock fan comes on and instantly I see cooling even in 90+ degree weather. Again, cleaning your radiator is probably the best solution. It's not terribly hard to remove but even if you don't want to remove the radiator, removing the shroud and using a pressure washer/compressed air on the area in between the condenser and radiator with go a long way. You should also blast it from inside the engine compartment to dislodge the crap that gets stuck in the radiator itself (it's amazing how much gets stuck in the fins). Be careful not to bend them.
